Statistical Assessment of Core Loss Measurement Techniques for Laminated Steel
Paper in proceeding, 2023
In this paper, a comparative study of core losses in laminated steel samples by means of inferential statistics is presented. In particular, core loss measurements taken upon Epstein Frame, Single-Strip tester, and Ring Core specimens at several frequencies and induction levels are compared via Analysis of Variance and two-sample t-tests. The hypothesis of a statistically significant difference among the testing procedures is sustained and ring cores showed a lower magnetic performance when compared to Epstein Frame and Single-Strip tester.
